RADIATOR.

Application led July 2,

To all 107mm t may concern:

Be it known that I, Janus W. MCFAR- LAND, a citizen of the United States, residing at Los Angeles, in the county of Los Ad ngeles and Fitate of California, have invented new and useful linprovements in Radiators, of which the following is a speciiication.

This invention relates to radiators such as are employed in connection with internal combustion engines.

It is the object of the invention to provide a radiator comprising independent core sections which may be readily detached from and connected to the headers of the radiator.

rllhe invention will be readily understood from the following description o f the accompanying drawings, in which- Figure 1 is a front elevation of a radiator constructed in accordance with the in vention.

Fig. 2 is an enlarged longitudinal section on the line 2-2 of F 1.

Fig. 3 is a detail section on the line 3 3 of Fig. 2.

Fig. 4 is an enlarged front elevation of Ione end of one of the radiator sections.

Fig. 5 is a transverse section on the line 5-5 of Fig. 2. y

The radiator comprises usual upper and lower headers 1 and 2, preferably, substanf tially rectangular in cross section and eX tending the width of the radiator. A plurality of core sections 3 are arranged along side one another between the headers, these core sections being each provided with side plates l arranged to form a unitary structure of the respective core sections and also adapt-ed when the core sections are placed in juxtaposition between the headers to form additional radiating surfaces.

The core sections are A.provided with means for connecting the sections to headers 1 and 2 so that individual core sections may be readily removed and inserted in posi.- tion. The connecting means at the respective ends of a core section is shown as a casting 5 consisting of angularly disposed sides 5a and 5b arranged to abut against the front of a header of the radiator and against the end of the core section respectively. The surface of a header against which the casting abuts is, preferably, inclined as shown at 6 and the abutting surface of the casting is similarly inclined as 1920. Serial No. 393,627,

shown at 7 with a gasket 6 interposed between saidabutting surfaces. The outer surface of the side 5a ofthe casting is provided with bossesff) through which bolts 10 may be received for detachably connecting the casting to the radiator header. 'lhese bolts extend through the casting and through the header of the radiator and are threaded into suitable bosses 11 providedupon the interior surface of the header. When the casting is thus'connected to the radiator header the side 5b thereof is arranged' to lie against the wall of they header, andv said side of the casting is permanently secured to the end` of a core section as by soldering. The side 5", preferably, lies flush against the end of the core section with the side plates 4L of the core section, preferably, extending along sideof the edges of the casting. f

A port 13 is provided in the inclined walls 6 of the radiator headers in alinement with each of the castings 5, and the side 5a of each casting is provided with a port 14 in its inner surface in alinement with port 13. The portl 14 communicates with the hollow interior 15 of the side 5- of the casting, which hollow interior communicates with a recess 16 provided in the outer surface of the side 5l of the casting. This recess communicates with the water channels through the core section to which the casting is secured. said casting being secured, to the core section at its edge 17 surrounding the recess 16.

lt will be observed that both the hollow interior 15, and recess 16, of a casting 5,

extend inwardly from the outer surface' of said casting, and are of such conformation that in casting the same, no interior core is necessary in the mold employed for the cast-ing operation. The mold will simply be provided with suitable protuberances upon its surface arranged to form the openings .through the casting, the casting being of such shape that it may be .readily removed froin the mold. f

I have thus provided an extremely simple construction. which will be inexpensive to manufacture, 'due to the simplicity of the mold employed, the castings when formed, being adapted to be permanently secured to t e respective ends of a core section to provide a removable structure detachably secured by bolts `l() to the radiator headers.

Various changes may bey made Withontfdeparting from "the spirit of the 'invention as claimed.

- Vhat is claimed l, A radiator'comprising headers having one of their vertical Walls inclined and formed` with an opening, bosses formed interiorly oi' the headers. 'adjacent to said openings, core sections between the headers, and connectingl members at the lends of the core sections, each of saidconnecting members 'having a horizontal portion communh eating' with the adjacent end 'oi1 the corresponding core section and a vertical portion tapered and adaptedzto contact with the inclined portion oif'tlie corresponding headers, said vertical portion"beiney in communication with the horizontal portion and With thel 'opening to the corresponding header, bosses `formed on the connecting,` members, and fastening` members'extending i said `walls, coie sections between'the headers, land"connecting `members at theendsoif the coresections, each of said connecting members having a-,horiZon-tal portion communicating' with the adjacent end of the corresponding core section and a vertical portion tapered and adapted to contact with the inclined portion of the corresponding' 3. A `radiator comprising headers, core sections, and connecting nienibei's 'at the ends oi sald core sect1on`s,"each connecting' member haring a side abuttlm'gfagainst the rinclined side of a headensaid abutting side being correspondinglyinclined, and means for detachably connecting said sides'to said headers. y

In testimony whereof- I'have signedvm'y name to this 'speciication JAMES lV. MCFARLND.
